چکیده

In this research we try and implement communication system using the metaphor of a door on the World Wide Web (WWW) as a media for novel types of informal communications. We call those informal communications through a door ”on-door communications.” As an on-door communication system, we have designed and implemented a system for a chat at a net door. One has a door page on WWW and a chat system is presented there so that the others pay a visit to have a chat at the door with two features for awareness, viz. knock and shadow. A knock on the door is used to let the others to notice of the arrival of a visitor at the door with an auditory signal. A shadow indicates the existence of visitors as well as that of the door owner. This paper reports on our design and implementation of our prototype system as well as its operations.
